Yield +Angle 
 
 
 
 
Selecting this strategy in “General data” tab of “Freedom wrenches Tightening program 
definition”, Freedom³ will detect automatically the yield point, after detection, user has to 
continue to tighten reaching a specific angle ( Nominal Angle).In case the Yiled point is not 
recognized, Freedom³ will display an error message.  The Angle value is counted starting from 
Yield point. The result will be considered “OK” if the angle and torque values will be in the 
tolerances (inside the green window). In this tightening strategy both parameters torque and 
angle values will be considered for statistic charts (wrench collects all time angle and torque 
values). 
 
Note  
This tightening strategy is available only for Fredoom³ SPC mode.

Fields And Meaning Table for “Freedom wrenches tightening program definition” Tool Tab: 
 
 
Fields Meaning 
Tool Nr. =t’s the identification number of the tool (end 
fitting) 
Torque Correction Factor =t’s a torque factor. User must fill this field only 
if on the wrench is plugged an extension that 
modifies the original calibration length. See 
figure below to calculate the factor< 
Angle Correction Factor =t’s an angle factor. User must fill tUis field  
Flexion Correction Factor =t’s the  angular error  due to the extension 
tool. user must measure it using a protractor or 
a rotary transducer mounted at the end of the 
extension (close to the joint) and see the 
different between the angle reading of the 
wrench and the angle  reading of the protractor 
or the rotary transducer. Example if the 
different is 3

In this page is possible to customize the percentage to light every single led on the wrench

- Click on Batch Tab  
 
 
 
 
 
 
Note: 
Inside Batch Tab is possible to multiply the number of screws to tighten. For example, usually to 
mount a wheel on the car there are 4 or 5 screws to tighten with the same strategy for all screws. 
=n this Tab is possible to define how many screws “Freedom³ has to tighten”.

See  table below  to fill correctly all fields. 
 
Fields Meaning 
Screws nr In this field, user has to indicate the number of 
screws to tighten with Freedom³ (for example if 
there are 3 screws, SQ-net will send to 
Freedom³ 3 time the same tightening program) 
Enable batch Click on check box in order to enable Batch 
function 
Strategy In this field is possible to define the strategy in 
order to drive the wrench considering the 
status of the tightening: 
Count only ok results-> selecting this option the 
wrench will consider the batch completed only 
if Freedom³ will get the number of batch all ok 
(for example if there are 3 screws to tighten, 
the batch will be completed only after getting 3 
ok results), All not ok results are not 
considerate for batch counting. 
In case of error redo the batch-> selecting this 
option all time operator get a not ok result, he 
must restart from the complete batch from the 
first screw, that means if there are 3 screws to 
tighten, if the user get a not ok result on last 
screw, he must restart the complete batch 
from the first screw (all the other results are 
not considerate). 
In case of error redo last operation->  selecting 
this option all time operator get a not ok result, 
he must retightening only the last screw.

How to create a route 
 
 
A route is a group of Control Quality test or tightening strategy. Freedom³ can receive Control 
Quality  route, Tightening Program route or both. To send tests or tightening programs from SQ-
Net to Freedom³, user must create a route in SQ-Net and send it. 
From SQ-Net front page, select route management icon:
